Airbag control unit with part number 77960-TGS-A110-M2

What does the airbag control unit 77960-TGS-A110-M2 do?

In the Honda vehicle, the airbag control unit 77960-TGS-A110-M2 controls the SRS restraint system. It evaluates the signals from the crash sensors, decides within milliseconds on the triggering of airbags and seatbelt pretensioners, and monitors the entire system.

The electronics show faults via the airbag warning light in the instrument cluster.

After an accident, the control unit stores crash data and locks itself.

Why does the control unit 77960-TGS-A110-M2 fail?

The most common cause is crash data stored after an accident, even if no airbag has fired, because a normal diagnostic tool cannot remove it. Other causes are aged components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes from a weak battery or a jump start.

As long as the crash data remains in memory, the fault stays recorded in the control unit. The unit reports the fault even if the accident was a long time ago.

The other causes concern ageing and environmental influences. Cold solder joints are hard to detect, while moisture and corrosion attack the contacts and voltage spikes put additional strain on the electronics.

How can you tell that the 77960-TGS-A110-M2 is defective?

The airbag warning light in the instrument cluster lights up permanently or only intermittently, and at the same time an error message may appear in the instrument cluster.

In addition, it becomes noticeable when the diagnostic tool cannot establish a connection to the control unit, or when a fault memory cannot be cleared.

As long as the defect exists, airbags and seatbelt pretensioners may fail to deploy in an emergency. The light shows the defect as soon as it occurs, so the warning must be taken seriously.

Comparing the part number on the label of the removed unit with this page only tells you about the correct unit. Having the fault memory read out beforehand, on the other hand, clarifies whether the control unit is defective or whether a plug or cable is behind it.

For the same vehicles, we also repair control units with the part numbers 77960-TGS-A010-M2.

How does the repair of the 77960-TGS-A110-M2 work?

First have the fault memory read out and enclose the log. Then disconnect the battery before the control unit is removed. Afterwards, create the repair order online and send the unit off well packed. Checking, repair and the function test at Airbag24 usually take 3–4 working days.

No step of this sequence may be skipped, because it serves safety.

At Airbag24 the unit goes onto the test bench, defective components are replaced during the repair, and stored crash data is erased. A function test completes the work, after which your own unit is sent back.

Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.

How does the control unit 77960-TGS-A110-M2 get to Airbag24?

A parcel is possible, as is a UPS collection that you book for an extra charge. The return of the repaired unit is made by UPS.

The printed repair order goes into the packaging, and the control unit should be packed shockproof.
